Subject: Pretreatment Review of Sewer Use Ordinance
Municipal NPDES Permittee: City of Dunn
Treatment Facility: Black River WWTP - NPDES #: NC0043176, Harnett County
Dear Mr. Trivette:
The Municipal Unit of the Division of Water Resources has reviewed the Sewer Use Ordinance (SUO) submitted on
behalf of the City of Dunn, NPDES Permit #: NC0043176, received by the Division on October 23, 2023.
The review indicates that the SUO is adequate and meets the minimum requirements of 15A NCAC 2H .0900 and
40 CFR 403.8 (f). The attorney's statement is filed with the SUO in the Division's record.
Please remember it is the responsibility of the POTW to continue efforts to ensure that any Significant Industrial User
(SIU), as defined by NCAC 15A 2H .0903(b)(30) (A) through (D), are identified and subsequently added to the
Town's pretreatment program. This includes evaluation of new lUs before they commence discharge and evaluation
of existing lUs determined to be not SIUs that make changes to their process.
Within 180 days of the effective date of any reissued/modified wastewater treatment facility permit, the Permittee
would be required to submit to the Division a written technical evaluation of the need to revise local limits (i.e., an
updated IWS, or documentation of why one is not needed). This action may include revising, updating, or adding to
the list of SIUs. Pursuant to 15A NCAC 02H .0907(b) either the Division or the permittee may initiate pretreatment
program revisions.
Thank you for your continued cooperation with the Pretreatment Program. If you have any questions or comments,
please contact Keyes McGee at 919 707-3626 / [e-mail].
